I
targeted an occluded boundary where the northern end of a dryline bulge
met with an outflow boundary near Ardmore, OK. A cold front was surging
southeastward across western and central Oklahoma. The trough was possitively
tilted and the shear was not favorable for supercells or tornadoes.
I was simply 'storm starved' and wanted to see some convection. Elevated
morning storms progressed eastward into Arkansas and a clear slot (large
clearing in the cloud cover) moved over central and eastern Oklahoma.
The moisture north of the boundary mixed with the warm air south of
the boundary and towers began to develop in the late afternoon/early
evening along the occluded boundary.

A
storm developed to the west of Ardmore and I drove on a small dirt road
west of the small town of Bromide, OK. I documented the small high-based
storm as it approached my location. It was a low-topped storm and had
a healthy updraft and dark rainshaft to its northeast. The storm was
clearly linear and I drove east through Bromide, OK to get a better
view with less trees.

picture on the right was taken west of Bromide, OK looking west at a
linear single-cell storm.

The
storm propagated eastward and I took a few photographs and some very
short clips of footage. I decided to let the storm overtake my location
and then proceed home. A strong west wind hit my location shortly before
the updraft base moved over verifying the storm was outflow dominant.
Pea and dime-sized hail occurred at my location as the rain/hail shaft
moved over accompanied by high winds. It was a good successful chase
even though supercells and tornadoes were not on the menu. Only the
day before I was in Arkansas chasing earthquakes (see 2/23/11 Arkansas
Earthquake chase here).

shaft on the right side of the photograph.
